AWS Service Prefix Lookup

Every AWS service that supports IAM has a short prefix string — the same string that appears before the colon in an action name (like "s3" in s3:GetObject) and as the service field in that service’s ARNs. AWS Service Prefix Lookup is a searchable reference mapping common service prefixes to their full AWS service names.

This table covers roughly 45 commonly used AWS service prefixes spanning compute, storage, database, networking, security, and developer-tooling services — a curated convenience reference, not AWS’s complete catalog of 300+ services. AWS documents the authoritative, complete list of service prefixes (along with each service’s actions, resource types, and condition keys) in its own Service Authorization Reference.

• ~45 curated service prefixes mapped to their full AWS service names.
• Live search across both the short prefix and the full service name.
• Explicitly labeled as a curated subset, not AWS’s complete service list.
• 100% client-side — nothing is sent anywhere.

1. Type a prefix or service name into the search box (e.g. "states", "step functions", "kms").
2. Scan the filtered table for the matching prefix and its full service name.
3. Clear the search box to see the full curated list again.

Example 1. Search "states" → AWS Step Functions.

Example 2 — search by full name. Search "kubernetes" → Amazon Elastic Kubernetes Service (EKS), prefix "eks".

Example 3. Search "elastic" → surfaces Elastic Load Balancing, EC2 Auto Scaling, ElastiCache, and ECR, all of which include "Elastic" in their full name.

• Fast prefix-to-name lookup while reading policies or ARNs.
• Search by either prefix or full name.
• Honest scope — clearly a curated subset with a pointer to AWS’s authoritative reference.
• Private — runs entirely in your browser.
